PUZZLE.

SPECIFICATION forming part of Letters Patent No. 496,263, dated April 25, 1893.

Application filed June 27,1892.

T0 LLZZ whom it may cm1/0cm:

Be it known that I, JESSE KINNEY, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Puzzles, of which the following is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in puzzles, and the invention consists in the peculiar construction and arrangement of two interlocking pieces, one piece having a retracted portion located between two enlarged portions or heads, and the other piece having an aperture corresponding to the size of the restricted portion, the head being made of material which is adapted to be compressed, all as more fully hereinafter described.

In the drawings, Figure l is a perspective view of my puzzle showing in one puzzle alternative forms of construction. Fig. 2 is a top plan view thereof. Fig. 3 is a cross section on linex in Fig. 2. Fig. 4 is a cross section on liney y, Fig. 4.

My invention comprises two of the locking pieces. Preferably one piece is made larger than the other and forms the supporting bodyA and it may comprise two pieces or more. I have shown it with the contracted portion B located between two heads C and D with the ring E having an aperture corresponding to the size of the restricted portion B, and I have shown it with an aperture through the head C, in which the block G was adapted to be secured, this block being provided with a restricted portion H located between the two heads I. f

I have found that some ordinary Woods, such as bass wood are very elastic and can be compressed with little trouble to halt` their normal size, and in carrying out the manufacture of my puzzle I make the supporting body A of such compressible material. The

head D I then place in a vise or wrench and compress it to the size of the restricted portion B and then the ring E will readily slip Serial No. 438,153. (No model.)

over the head onto that restricted portion. As soon as it has engaged the restricted p01'- tion I dip the head into water, preferably warm water and it will quickly and almost instantly assume its normal shape and size.

Where the body portion is apertured and the detachable block has a restricted portion engaging through the aperture, the body may in that case be made of rigid material,whilethe detachable block is made of compressible or elastic material, or the heads I may be made of such material.

I have found by experiment from exhibiting such a puzzle to a very large number of people that no one appreciates the compressibility of the wood and therefore is not able to find any way of solving the puzzle as it seems impossible from inspection to separate the parts without breaking one or the other.

What I claim as my invention is- A l. A puzzle composed of two interlocked pieces, one piece having a restricted portion, and two heads or enlarged portions formed of compressible fibrous material having the appearance of a rigid non-compressible substance located at opposite ends of the restricted portion and the second piece formed with an aperture corresponding to the size of the restricted portion, substantially as described.

2. A puzzle composed of two interlocking pieces, one piece being made of wood, a compressible portion formed thereon, composed of a material having an appearance of arigid non-compressible substance two heads or enlarged portions located at opposite ends ot'l the restricted portion, and a second piece formed with an aperture corresponding to the size of the restricted portion and adapted to be engaged over the head when the same is compressed, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses. JESSE KINNEY. Witnesses:
